If your jade plant has black spots on its leaves, it could be a sign of several potential problems, from fungal infections to insect infestations. In this article, we’ll explore some of the common causes of black spots on jade plant leaves and offer solutions to help you restore your plant to its former health.

Causes of Black Spots on Jade Plants


One of the primary causes of black spots on jade plants is overwatering. Jade plants are succulents that prefer to have their soil dry out between waterings. Overwatering not only encourages the growth of fungi and bacteria, but it can also lead to root rot, which can cause black spots on the leaves. To prevent this issue, it is essential to water the jade plant only when the soil is dry to the touch and ensure proper drainage [source].


Another common cause of black spots on jade plants is sunburn. Jade plants thrive in bright, indirect light but can develop sunburn if they are exposed to direct sunlight for extended periods. Sunburn shows up as dark spots on the leaves and can result in the leaves turning black and dying [source].

To protect your jade plant from sunburn, position it in a well-lit area with indirect sunlight. If the plant is outdoors, consider providing shade during the hottest parts of the day or gradually acclimate it to the increased sunlight to avoid sunburn.

While overwatering and sunburn are two major causes of black spots on jade plants, other factors, such as pests and diseases, can also contribute to the issue. By ensuring proper care and monitoring your jade plant closely, you can address any problems early on and maintain the health of your plant.

Preventing Black Spots

Preventing black spots on your jade plant is essential to maintain its health and appearance. This can be achieved by adopting appropriate watering techniques, ensuring proper sunlight exposure, and using clean gardening tools. By following these guidelines, you can keep black spots at bay and your jade plant thriving.

Proper Watering Techniques

One of the primary reasons for black spots on jade plants is improper watering or overwatering, especially during their dormant period in winter. Jade plants need less water during winter, so it is crucial to adjust your watering schedule accordingly. Ensure that the soil is well-draining and avoid letting your jade plant sit in standing water for an extended period. This practice helps reduce the chances of fungal growth, ultimately preventing black spots from occurring on the leaves.

It’s worth noting that the jade plant is a succulent, meaning it stores water in its leaves. Therefore, allow the soil to dry out between waterings, making sure not to overwater.

Sunlight Exposure

Another factor that contributes to the prevention of black spots on jade plants is sunlight exposure. Jade plants typically thrive in bright, indirect light. Providing adequate sunlight will help reduce the chances of fungal infections, leading to black spots on the leaves. It’s essential to expose your jade plant to morning sunlight and protect it from direct afternoon sun to prevent scorching.

Rotate your jade plant regularly to ensure that all sides receive an equal distribution of sunlight. This practice encourages even growth and reduces the likelihood of black spots developing due to insufficient light exposure.

Treating Black Spots

Black spots on jade plants can be caused by several factors such as overwatering, poor drainage, pest infestations, or fungal and bacterial infections. Knowing how to treat these black spots will help improve the health of your jade plant.

Removing Damaged Leaves

Begin by inspecting the leaves of your jade plant and removing any with black spots. Use clean gardening shears to cut off affected leaves to prevent the spread of disease and damage to healthy parts of the plant. Dispose of the damaged leaves properly to avoid contamination of the soil or other plants. After removing the damaged leaves, clean the shears with a disinfecting solution to kill any remaining bacteria or fungal spores.

Applying Fungicides

Fungal infections can cause black spots on jade plants, so it’s essential to treat the plant with a fungicide. Choose a suitable fungicide for your jade plant by checking labels for specific fungal diseases that affect jade plants. Follow the instructions on the product packaging for the correct application rate and method.

  • For a mild infection, a homemade fungicide solution can be used. Mix one tablespoon of baking soda with one quart of water and a few drops of mild liquid soap. Spray the solution on the affected plant, making sure to cover all surfaces, including the underside of the leaves.
  • For a more severe infection, consider using a commercial fungicide product from a local garden center. Always follow the manufacturer’s instructions for proper application and safety precautions.

Be sure to treat your jade plant as soon as you notice the black spots to avoid further damage and restore your plant’s health.
